Run a Manual Battery Test
To run a manual Battery Test:
1. Go to
System > FXM System > System Functions > Battery Test
. Note that you must have a
battery subsystem defined in the FXM System in order to have this menu item available under
System Functions
.
2. From the Configuration table, set the Termination Voltage and Timeout values.
Which ever or these two conditions occurs first will terminate the battery test.
3. From the Status table, press the Start Manual Battery Test command.
To start a battery test, the
Battery Mode
must be in the
Float
mode, otherwise the battery test
cannot start.
There are a number of reasons why the test might terminate early. Two examples are:
– Detection of a weak battery - where the voltage drops too quickly.
– AC failure.
If Battery Runtime and Health Estimation is enabled you should see the battery state of charge
(SOC and runtime remaining (RTR, update during the test. If the test runs long enough, the test results
should be stored in the Battery Log page.
The Battery Runtime Remaining algorithm attempts to calculate an accurate prediction of the
remaining battery runtime. An accurate estimate of the battery health requires at least one discharge
greater than 20% from when the unit is switched on.
When the unit is powered on, the algorithm assumes that a new battery is connected to the unit. Each
discharge greater than 20% will result in a new calculation for the relative battery health. This value is
used in the Battery Runtime Prediction algorithm to compensate for an aging battery. It is recommend
the user set up a battery test with a depth of discharge of at least 20% every six months or so.
The
Battery Runtime Remaining algorithm uses the battery voltage to predict the remaining runtime.
Battery voltage changes rapidly during the first few minutes of discharge due to charging and
discharging while the unit is in Inverter mode. This results in a less accurate predicted runtime. The
battery voltage may change rapidly during the last 20% of the discharge when the battery is almost
drained.
Schedule a Battery Test
To schedule a Battery Test:
1. Go to System > FXM System > System Functions > Battery Test .
2. From the Automatic Testing table, set the number of days between testing.
3. Set the start hours.
4. Set the number of days to wait before retrying to run a failed battery test.
5. Click on
Reschedule Next Time to schedule the next battery test.
